What are some use cases for this besides the car battery monitor/alerts?
I work on electric steering systems. There's a lot of info on the OBDII bus--depending on the complexity of the device and your particular vehicle, you could use it to track driving habits/efficiency, location, interpreting trouble codes, and plenty more. If it has some local data logging, it could even be used as a "black box" in the case of an accident.
My first thought was a self hosted black box type device. But I didn't see a GPS option listed. Sounds like it would be really useful as a vehicle monitor as well. Could catch issues and provide logs.
The device might not have GPS, but your vehicle might. It's a matter of what info your vehicle has available, and if you're able to interpret it (i.e., if you have the network spec available). Lots of possibilities either way.
I have a friend who set things up to calculate gas mileage, and used it to get into better driving habits.
